v0.45.0

# GPT 5.3 Codex + Gemini 3 thinking levels

On this release we're shipping a few model improvements + small fixes.

## GPT 5.3 Codex

This was just made available via API by OpenAI today, and it's already available in Crush. Just open the model picker and choose it.

## Gemini 3+ thinking levels

Gemini 3 and 3.1 not support thinking levels. Before we only had an on/off toggle for thinking, but now you can choose levels for Gemini:

## Other highlights

* This is for Rustaceans :crab:. Crush won't attempt to start the `rls` LSP automatically anymore. `rls` was deprecated in favor of `rust-analyzer`, which will still be used automatically used if installed.
* @0xarcher fixed an issue that made some MCP server failing to start.
* @huaiyuWangh made a great job fixing a good number of small bugs related in the agent.

<summary>Verifying the artifacts</summary>

First, download the [`checksums.txt` file](https://github.com/charmbracelet/crush/releases/download/v0.45.0/checksums.txt) and the [`checksums.txt.sigstore.json` file](https://github.com/charmbracelet/crush/releases/download/v0.45.0/checksums.txt.sigstore.json) files, for example, with `wget`:

```bash
wget 'https://github.com/charmbracelet/crush/releases/download/v0.45.0/checksums.txt'
wget 'https://github.com/charmbracelet/crush/releases/download/v0.45.0/checksums.txt.sigstore.json'
```

Then, verify it using [`cosign`](https://github.com/sigstore/cosign):

```bash
cosign verify-blob \
  --certificate-identity 'https://github.com/charmbracelet/meta/.github/workflows/goreleaser.yml@refs/heads/main' \
  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
  --bundle 'checksums.txt.sigstore.json' \
  ./checksums.txt
```

If the output is `Verified OK`, you can safely use it to verify the checksums of other artifacts you downloaded from the release using `sha256sum`:

```bash
sha256sum --ignore-missing -c checksums.txt
```

Done! You artifacts are now verified!
